22. Harnessing coherence in femtosecond fluorescence for photon diagnostics and future X-ray sources

Invited speaker

This talk will focus on coherence properties of femtosecond fluorescence produced by pumping the transition metal elements with X-ray free-electron laser (XFEL) pulses.

When the intensity of the incident beam is sufficiently low, the fluorescence will be incoherent light. The higher-order coherence of such incoherent light, especially intensity correlation between separated positions,...

Coherent X-ray diffraction imaging (CXDI) is a powerful method for visualizing the structure of an object with a high spatial resolution that exceeds the performance of the lens. CXDI is of several types, based on the optical systems and reconstruction methods. Plane-wave CXDI, in which a coherent planar beam is incident on a sample, can be used to observe isolated objects. Nonetheless,...

Oral

X-ray ptychographic tomography is now routinely used at synchrotron facilities around the world, producing nanoscale resolutions in 3D. However, the acquisition times still lag significantly behind other imaging methods. As many synchrotrons upgrade to diffraction limited rings, the community is being presented with a dramatic increase in the coherent flux available. However, translating that...

43. Development of 5.04 Mpixel CITIUS detector for high-resolution ptychography

Oral

We have developed and deployed CITIUS detectors for the XFEL facility SACLA and the synchrotron radiation facility SPring-8. At SACLA, we are building a 20.2 Mpixel detector system that can run at a maximum frame rate of 5 kHz. The CITIUS detectors for synchrotron radiation applications were demonstrated to operate at the maximum frame rate of 26.1 kHz at the full-image readout condition and...
